Live update of stdout/stderr from running jobs.
Live update of stdout/stderr from running jobs.

Automatically update stdout/stderr from running jobs by connecting
to PIPEd output from Popen.

This implementation uses two threads to listen to stdout/stderr
as otherwise an empty buffer on either one will block any further
updates when attempting to read it.
